A classical handcoated paper cone and matching natural rubber surround produce
a well behaved roll off characteristic and reduce potential resonance problems.
A long, high temperature voice coil wound on an aluminium voice coil former
gives low distortion and high power handling capacity.
The large magnet system provides high effi ciency and good transient response.
A bumped backplate in the magnet system allow maximum utilization of the
long voice coil without mechanical limitation.
Extremely stiff and stable injection moulded metal basket keeps the critical components
in perfect alignment. Large windows in the basket both above and below the
spider reduce sound refl exion, air fl ow noise and cavity resonance to a minimum.
